Hi,

Try to repair avast! You can do it by going to…

Control Panel → Programs and Features (Add or Remove Programmes) → avast → Click on uninstall /Change ->Scroll down for the option of Repair .

Try to scan with avast! and post back with results.

Maybe try to enter the settings → Troubleshooting → restore factory defaults → reset now

After the repair, reboot.
